Jack should arrange the beads close together and slide past each other to represent water molecules in a liquid.
<h3>How are the molecules of water arranged when water is in its liquid phase?</h3>
- Each water molecule contains two atoms of hydrogen and one atom of oxygen, arranged such that one side of the molecule (nearest the hydrogens) is positively charged while the other side (nearest the oxygen) is negatively charged.
- They’re arranged randomly, and in random motion.
- In fact, they’re not even keeping the same hydrogen atoms, as they are constantly popping off and reforming on the nanosecond time scale.

Answer:
Nucleotides make up DNA, or deoxyribonuleic acid.
Explanation:
<span>Infiltration is the process by which rainwater becomes groundwater. In the water cycle, which involves primarily; evaporation, condensation and precipitation. Henceforth, after precipitation comes infiltration in the land areas leaving the rainwater aggregated in a single location which accumulates over time. Then this process is followed by runoff and subsurface flow by which water flows through other bodies of water, either in river, sea or ocean, even lake. Other rainwaters that has segregated and wasn’t able to transport itself stays in the process of infiltration, thus groundwater.<span>
Thus, solar radiation doesn't play a role in runoff or infiltration.

Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
